From 3ee16518618ee73cc0d4e0b2e47124dc83adfe5d Mon Sep 17 00:00:00 2001 From: "mhansson@dl145s.mysql.com" <> Date: Thu, 31 May 2007 14:22:21 +0200 Subject: [PATCH] bug#27741: udf test fails on AIX < 5.3 problem #1: udf_example.so does not get built on AIX solution#1: build it yourself using cd sql; gcc -g -I ../include/ -I /usr/include/ -lpthread \ -shared -o udf_example.so udf_example.c; mv udf_example.so \ .libs/ problem#2 (the bug): udf_example fails because it does not recognize the variable LD_LIBRARY_PATH when doing dl_open(), it looks at LIBPATH solution#2: add the library path to LIBPATH problem#3: udf_example returns the wrong result length since it relies on strmov to return a pointer to the end of the string that it copies. On AIX builds, where m_string.h is not included (m_string defines a macro expanding strmov to stpcpy), there is a macro expanding strmov to strcpy, which returns a pointer to the first character. solution#3: define strmov as stpcpy. problem#4: #2 applies on hp-ux as well, but this platform looks at SHLIB_PATH solution#4: added the library path to SHLIB_PATH --- mysql-test/mysql-test-run.pl | 11 +++++++++++ sql/udf_example.c | 3 ++- 2 files changed, 13 insertions(+), 1 deletion(-) diff --git a/mysql-test/mysql-test-run.pl b/mysql-test/mysql-test-run.pl index c494626bbae..85191a0be00 100755 --- a/mysql-test/mysql-test-run.pl +++ b/mysql-test/mysql-test-run.pl @@ -1784,6 +1784,17 @@ sub environment_setup () { split(':', $ENV{'DYLD_LIBRARY_PATH'}) : ()); mtr_debug("DYLD_LIBRARY_PATH: $ENV{'DYLD_LIBRARY_PATH'}"); + # The environment variable used for shared libs on AIX + $ENV{'SHLIB_PATH'}= join(":", @ld_library_paths, + $ENV{'SHLIB_PATH'} ? + split(':', $ENV{'SHLIB_PATH'}) : ()); + mtr_debug("SHLIB_PATH: $ENV{'SHLIB_PATH'}"); + + # The environment variable used for shared libs on hp-ux + $ENV{'LIBPATH'}= join(":", @ld_library_paths, + $ENV{'LIBPATH'} ? + split(':', $ENV{'LIBPATH'}) : ()); + mtr_debug("LIBPATH: $ENV{'LIBPATH'}"); # -------------------------------------------------------------------------- # Also command lines in .opt files may contain env vars diff --git a/sql/udf_example.c b/sql/udf_example.c index 2bb4fe92d2f..0f28c2a14b0 100644 --- a/sql/udf_example.c +++ b/sql/udf_example.c @@ -130,7 +130,8 @@ typedef long long longlong; #include /* To get strmov() */ #else /* when compiled as standalone */ -#define strmov(a,b) strcpy(a,b) +#include +#define strmov(a,b) stpcpy(a,b) #define bzero(a,b) memset(a,0,b) #define memcpy_fixed(a,b,c) memcpy(a,b,c) #endif
